. STANDING-VALVE FULLER.

Application filed December 19, 1927. Serial No. 241,239.

' The present, invention relates to improvements in standing valvepullers and has for its principal object to provide a simple andeflicient device which is capable of remov ing the standing valve fromthe lower end of the working barrel without necessitating the removal ofthe working barrel from the -ground.

One of the important objects of the present invention is to provide astanding valve puller which is simple in construction, in expensive,strong and durable and'further well adapted'to the purpose for which itis designed.

' Other objects and advantages will become apparent from the followingdescription taken in connection with the accompanying drawing.

In the accompanying drawing forming part of this specification, and inwhich like numerals indicate like parts throughout the same: I Figure 1is an elevational view of the standing valve puller embodying myinvention showing the same attached to a standing valve just prior tolifting the standing valve upwardly out of the working barrel.

Figure 2 is a vertical sectional viewthro'ughthe sleeve that forms animportant part of the present invention, showing the expansible coilspring arranged therein.

Figure 3 is a bottom plan view of the sleeve, and

Figure 4 is a detail perspective view of the screw member that alsoforms a salient part of .the present invention.

In the,drawing wherein for the purpose of illustration is shown thepreferred embodiment of my invention, the numeral 1 designates the lowerportion of a working barrel of a pump that is used in conjunction withthe drilling of oil ,wells and seated in the lower end of this workingbarrel is the conventional standing valve 2. A cage 3 is associated withthe upper end of the-standing valve for housing the ball valve 4 and isformed in its top with a tapered threaded opening 5, the purposeof whichwill be presently apparent.

My improved standing valve puller comprises a sleeve 6 that is ofadiameter slightly less than the inner diameter of the working barrelland the upper end of this sleeve is internally threaded as at 7 forattachment to the lower end of the travelling valve 8,

the lower end portion of which isdisclosed in Figure 1 of the drawing.It is of course to be understood that the-traveling valve is of theconventional construction and is carried by the lower end of the suckerrod in the manner well known in the art. An annular shoulder 9 is formedon the interior of this sleeve 6 adjacent the lower end thereof, andthis is clearly illustrated in Figure 2. An expansible coil spring 10 isarranged within the sleeve and rests on the shoulder, the upper end ofthe coil spring being adapted to engage the lower end of the travelingvalve 8 which is threaded in the upper threaded end 7 of the sleeve.

The lower end of the sleeve is furthermore formed with a pair ofdiametrically opposed bayonet slots 11 and 12 respectively. The lowerends of the vertical portions of these slots terminate at the bottomedge of the sleeve as clearly illustrated in the drawing. The purpose ofthe bayonet slots will also be presently apparent.

The invention further comprehends the provision of a screw member 13,the lower" end of which is reduced and threaded as at 14 with referencemore particularly to F igure 4, the upper end of this screw member isrounded and pins 15 and 16 extend laterally from the upper portion ofthis screw member at diametrically opposite points.

The reduced threaded lower end 14 of this out'of the tubing and the wellstops pumping; When sand has cut and damaged the standing valve, it isnecessary to pull out the entire tubing from the ground to get to the fstationary standing valve, and this necessitates the expenditure of aconsiderable amount of time and labor. Hbwever, by providing a standingvalve puller or extractor of the character such as shown and abovedescribed, it will not be necessary to remove the working barrel ortubing from the earth. The standing valve has the screw member threadedtherein before the standing valve is initially inserted in the lower endof the working barrel.

The sleeve 6 is carried by the lower end of the traveling valve and thespring 10 will normally be expanded so as to engage the shoulder 9 atone end and the lower end of the traveling valve at its opposite end,this sleeve will act as a part of the traveling valve and the usual cupsare arranged on the traveling valve. The traveling valve will hold thefluid on its upstroke and take in fluid on its down stroke. The valveassociated with the standing valve works oppositely from the valve thatis associated with the traveling valve, the two together holding all ofthe fluid that is sucked into the tubing at all times.

It is of course, understood that the sleeve is disconnected from thepins 15 and 16 of the screw member during the ordinary operation of thesucker rods and the traveling valve carried on the lower end thereof andto which is secured the sleeve 6.

Should it become necessary to remove the standing valve from the workingbarrel, the sucker rod elevators on the top of the tubing (not shown)and sucker rod are forced downwardly so that the sleeve .6 will movedownwardly in the working barrel and when the open lower ends of thebayonet slots are in registry with the respective pins carried by thescrew member 13, said pins will then be positioned in the slot so thatthe horizontal portions of the bayonet slots are in alinernent with thepins, and when the sleeve is slightly turned, said pins will be disposedin the horizontal portions of the respective slots, thereby locking thesleeve to the screw member and to the standing valve. Simultaneouslywith the connecting of the sleeve to the screw member, the pins 15 and16 Will compress the spring 10 in the manner shown in Figure 1 and exertthe necessary tension to retain the pins in the horizontal portions ofthe respective bayonet slots so that when the traveling Valve is raisedupwardly out of the well, the standing Valve will also be raised andremoved.

After the necessary repairs have been made, the standing valve isdropped into the working barrel, and the same will again be seated areset and the traveling valve in a stationary mannerv in the bottom of theworking barrel for further use.

It will thus'be seen from the foregoing description that I have provideda standing valve puller which will at all times be positive andefficient in its operation and which will furthermore save considerabletime and labor in removing a standing valve and making the necessaryrepairs without necessitating the removal of the working valve from theground.

While I have shown the preferred embodiment of my invention, it is to beunderstood that various changes in the size, shape and arrangement ofparts may be resorted to without departing from the spirit of theinvention and the scope of the appended claim.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is In combination, a working barrel, a standingvalve unit removably seated in the bottom of the barrel, a reciprocabletraveling valve operable in the barrel, a sleeve carried by the lowerend of the traveling valve, said sleeve being formed at its lower endwith a pair of diametrically opposed bayonet slot-s, an an- ,nularshoulder formed on the interior of the lower portion of the sleeve, anexpansible coil spring arranged within the sleeve and disposed betweenthe shoulder and the lower end of the traveling valve, a member rigidlysecured at its lower end on the top of the standing valve, and laterallyextending pins carried by the upper portion of the member forcooperation with the bayonet slots to connect the sleeve to said memberwhereby the standing valve may be removed from the lower end of theworking barrel when the traveling valve is raised upwardly out of thebarrel, said expansible coil spring being compressed by the pins whenthe same are engaged within the slots so as to secure said pins withinthe circumferential portions of the slots.

In testimony whereof I affix my signature.
